As shown in the above table, ISO15693 supports 10 to 30% ASK or 100% ASK. A higher modulation index would lead to a higher bandwidth and lower range and a lower modulation index would result in low SNR.
How to select the right modulation index for an application?
2. How to configure 100% modulation index as the Table 32 of datasheet shows configuration bits for 0.5 to 60% only?
3. Does the data rate have an impact on the range?
